Cant see games on a LAN

I have 2 machines and neither can see each other on a LAN to host a game

from Demigod Forums

Hi

I have 2 machines and neither can see each other on a LAN to host a game, Any suggestions?both versions are the same and both have been playing other games together without issue. 

I only have one licence of the game but i would like to show a friend the multiplayer while he is here and I thought it should be possible.

 

Thanks

Have you allowed demigod through any software firewalls you have?

Yeah, tried looking for that. even shut down the firewall.

Same problem here. Ran wireshark on both machines. Client is sending UDP broadcast from port 1075 to 15000. Server is responding directly (15000 to 1075). Packets back and forth continuously. Nothing comes up on the screen.

The only possible problem is that the server response is fragmented.  But then you'd already be handling that, since at 1800 bytes, it's bigger than a standard Ethernet frame.

Nice text-based protocol btw, all the server details are there in the clear.  Easy to debug I'd imagine.

Will look into setting port ranges manually.

Changing the port ranges didn't have the desired effect.  All firewalls are off and messages are obviously getting through the router. Changing who is host and who is joining doesn't fix the problem.

Is there any debug I can look for or turn on in Demigod to see why the joining client is ignoring the packets it is receiving from the host?

Should I raise a ticket for this issue? Is there any information I can provide to help troubleshoot?

Hey there, I had a similar problem. I'm using Vista, and it hates me. I don't use any securtiy, but every now and then Windows Firewall decides that it's on (It's always off though). Even with the firewall being off, try to add Demigod to your firewall exceptions, and just generally make sure to give it a good talking to so that it knows to stay off, for real this time.

Maybe they can add a join by IP option, sometmies you can most likely connect to the game even if it isn't broadcast in your list.

More info now.  One machine is Vista64, the other XP32.  The XP machine is not responding to packets, whereas the Vista one is.  I conclude that something is wrong on the XP machine.  The XP machine seems to be listening on all the right ports (netstat -a reports 15000 and 6073 in the listen state). 

We're currently uninstalling the firewall, since disabling it doesn't seem to work (it doesn't report that it's blocking anything, but who knows).

Success.  Note folks, make sure that you have XP sp3.  Uninstall your firewall, especially if it's Comodo, disabling it might not work.

Same problem here and I've come to the same solution. Comodo firewall running, on both the Vista and XP (SP3) machine.

Completely uninstalling the firewall works, disabling it does not.

Solution: Open up comodo. Go to the firewall section. Go to Advanced. Open Attack Detection Settings. Go to the Miscellaneous tab. UNCHECK "Block Fragmented IP datagrams". Apply
